* dt-bindings: usb: atmel: Add Microchip LAN9662 compatible stringHerve Codina2022-07-051-0/+3
| | | | | | | | | | | | | The USB device controller available in the Microchip LAN9662 SOC is the same IP as the one present in the SAMA5D3 SOC. Add the LAN9662 compatible string and set the SAMA5D3 compatible string as a fallback for the LAN9662.

* dt-bindings: Remove leading zeros from bindings notationMarco Franchi2017-11-091-2/+2
| | | | | | | | | | | | | | | | Improve the binding example by removing all the leading zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"` Some unnecessary changes were manually fixed.

* | usb: atmel_usba_udc: Rework at91sam9rl errata handlingBoris Brezillon2015-01-121-1/+4
|/ | | | | | | | | | | | | | | | | | | at91sam9rl SoC has an erratum forcing us to toggle the BIAS on USB suspend/resume events. This specific handling is only activated when CONFIG_ARCH_AT91SAM9RL is set and this option is only set when building a non-DT kernel, which is problematic since non-DT support for at91sam9rl SoC has been removed. Rework the toggle_bias implementation to attach it to the "at91sam9rl-udc" compatible string. Add new compatible strings to avoid executing at91sam9rl erratum handling on other SoCs.
